I have done Hai Van Pass twice so after the climb stay up the top for 30 minutes or so walk around the old bunkers have a drink,then when you head into Danang on the right in the main street is a place called Mollys Coffee on a corner stop there for a feed before you head to Hoi Ain.
I stayed in the town before the pass so I could get a early start I think town is Lang Co Beach or something like that.
